Dave -
Who knows, maybe one of these days they will have to have a "DE-stabilizing effect" to achieve early 21st century "wobblycam" video!
Anyone that was around during the days of 35mm (that’s film, not sensor size) will remember the various types of “soft focus” filters available so I’m sure you’re correct.

Hey, since you thought of it first here maybe you could could shoot for a patent on “Daves Retro Wobblycam”!

I confess, I was one of those guys. I had a Kokin plastic filter kit just to degrade my Nikon glass. Of course they were reserved for shoots when girls were taking clothes off so they were justified!

And shaky cam is a professional style already. The show The office is the biggest example of it. I hate it.
